They all have an x2 rating which means they are appropriate for the application across the hot to neutral lines.

OK.  So you're saying these are the proper ones?

[JDUBS]

Define proper.  They are x2 rated caps.

recommended for this project.  The "best"!

This is the series that was originally speced,I don't know which is best sonically speaking.

Thanks.  Hmmm.  I might have to call my Vishay contact on this one.   

[Big Red Machine]

Where did the name Felix come from?  The Cat?  Why?

[jtwrace]

Here is the answer from my Vishay contact.

The 338 1-serie is an X1 cap 440Vac

The 338 2-serie is an X2 cap 310Vac

 

Both series are not the same.

The 338 1-serie is used in industrial applications (3 phase)

When the 338 2-serie is for standard applications (1 phase)

Where did the name Felix come from?  The Cat?  Why?

The original Lab power conditioner project was called Felicia, in honor of JoshK's wife. Based upon Jon Risch's Q&D digital filter, it used surplus back to back transformers to supply filtered balanced power to source components < 100va. The follow up project, less limited in current capabilities, smaller, using off the shelf parts, and with overall better performance was simply given the masculine version of the name Felicia, Felix.

a male given name: from a Latin word meaning “happy, lucky.”

The X1 rating is implicitly higher than an X2's, and an X1 can be used anywhere an X2 is called for. The reverse is not true. This would provide a higher in circuit dV/dt from the X1 cap assuming equal dV/dt s at rated voltages.

Quoted GBB:

"I listed the CMC part number.  A quick google search would have turned up the following data from Coilcraft's website.  Use the CMC with the appropriate ratings for your application.  As others have noted, the current draw of the Squeezebox is minimal, so the 3717 seemed like the right choice here.

I'm late coming to this thread.  I just checked CoilCraft and they have the P3717-a on backorder.  Obviously there are other options, but not understanding what they do, I am reluctant to substitute.  What if the effect of changing values?

You want part # P3717-AL that is the RoHs part #.

That's why it's on backorder.

Thanks- order placed

where can i puchase others  P3717-AL or sustitutes (cheap ones)

Scott. Have you ordered a 36 pcs tray (of Coilcraft p-3717)? If so, could you sell me 5 of them?

You know that you can purchase as little as you like.  RIght?

Sorry, I just order one to build out one Felix and see if it does what I am looking for.

Thank ya Paul!  I was going to go and make a label for my Felix unit using Felix the cat photo.  Not that it has anything to do with this but it looks cool.

I finished the first unit this morning after delays from other projects.
